Good news for both companies. I'm a bit surprised, because I thought VW would be pissed at Rivian that the R3 basically looks like a 1991 VW Golf[1] Country[2].
VW mostly stopped using the Rabbit name in 1985. It briefly made a come back in 2006 - 2009 for the Golf Mk5. The 1991 model would have been the Golf in NA. My parents purchased a 1987 VW Golf new which I then purchased from them in 1990 when leaving college. I owned it for another 4 years.
So perhaps Land Rovers are a better comparison? It surely reminds me a lot of the design of the Evoque which is quite small by Land/Range Rover standards.
